Influence of Strain and Spin-Orbit Interaction in a Cylindrical Quantum Point

Abstract

In this work study how the strain and spin-orbit Rashba interaction type affect the energy levels of the conduction band in a cylindrical quantum dot, using the 2x2 method k.p. The results show that the spin-orbit interaction strongly influences the energy levels of lifting the degeneracy even in zero magnetic field, while the strain compressing the levels enhance the Rashba interaction effects. In this context, the intraband optic absorption becomes a useful tool to study the effects of spin-orbit interaction and the strain on the electron energy levels.
